3. Select the channels to be logged in the Select channels to log section:

this group. Logging the power supply will provide values for the battery level. An alarm could
be set at a specific level to alert the account manager of a low level, thus prompting a field
visit to change the batteries and prevent lost data. If the logger contains a port for a rain
gauge, the Rain channel is also shown. To include a Logger channel in the datalog, select the
check box next to the channel name.
b. Expand the tree for each Port[1](Sensor Name) channel group to view the available channels
for the sensor. If the check box next to Logger or Port[1] is selected, all of the channels in the
group are automatically selected.
c. To include a Sensor channel in the datalog, select the check box next to the channel name.
The log channel count increases each time a channel is selected.
Note: For loggers with multiple sensor ports, the port number is added to the channel name. For example,
Velocity 3 is the velocity channel name for sensor port 3.
4. To set the logging interval for a channel group:
a. Click on the channel group name, for example Port1 (Flo-Dar) . The logging intervals are
shown.
